The Blackout Effectors Whetstone Analog Phaser combines old-school circuit design with modern design and parameters, all put into an industrial-strength box built to last a lifetime. This pedal is more than just a phaser; it has pitch vibrato capabilities, ring modulation, octave effects, and any combination of these to create some killer signature sounds. For analog tone with tons of filters, modes, and a true bypass switch, there's nothing better than the Whetstone Analog Phaser by Blackout Effectors.
